Hi All,

I am trying to follow the tutorial http://golang.org/doc/debugging_with_gdb.html.
But I ran in to this error.

ggarg:regexp gaurav$ gdb 6.out -d $GOROOT
GNU gdb 6.3.50-20050815 (Apple version gdb-1705) (Fri Jul 1 10:50:06

Dwarf Error: wrong version in compilation unit header (is 3, should be
2) [in module /Users/gaurav/apps/go/src/pkg/regexp/6.out]

I understand it is not golang issue. It is an old debugger on my
system which came with Xcode. I wanted to know can I simply install a
new version of gdb with out messing with Xcode settings?

Thank you very much.

Did you try download and compile it?

$ curl -O http://ftp.gnu.org/gnu/gdb/gdb-7.3.1.tar.gz

$ tar -xzf gdb-3.7.1.tar.gz

$ cd gdb-7.3.1

$ ./configure

$ make

$ [sudo] make install

Awesome. The new gdb got installed as: /usr/local/bin/gdb. Now it
works fine.
Thanks

I ran into this a while back http://tinyurl.com/5vxljc7 and had
similar concerns.

You don't have to install gdb to run it. Just build it, copy the
executable wherever you want it, then run it with an absolute path (I
kept the destination folder out of my search path).

- $ mkdir $HOME/gdb
- after gdb finishes building $ cp gdb/gdb $HOME/gdb/gdb
- then from the go executable's folder $ $HOME/gdb/gdb 6.out

Once I figured out the newer version wouldn't cause a problem I
installed it in /usr/bin

Yes I also use absolute path of gdb 7.3.1 default gdb still points to
old xcode ones.

-Thanks

I put /usr/local/bin before /usr/bin, so I can just remove the gdb from /usr/local/bin to go back to the gdb executable provided by xcode.
